  3. air pressure
  4. Low
  5. warm front
  1. a a body of air that has about the same temperature and moisture throughout
  2. b moving weather front along which a warm air mass slides over a cold air mass, producing stratiform clouds and precipitation
  3. c the movement of a fluid, caused by differences in temperature, that transfers heat from one part of the fluid to another
  4. d the weight of the air above an object
  5. e Area of low pressure where wind will move towards, associated with cloudy and rainy weather and air that is rising

5 Multiple choice questions

  1. the resistance encountered when one body is moved in contact with another. Slows down the speed of wind when it flows over land
  2. forms when cold air moves under warm air which is less dense and pushes air up
  3. a line on a weather map that joins points having the same barometric pressure
  4. an instrument that measures wind speed
  5. The way Earth's rotation makes winds in the Northern Hemisphere curve to the right and winds in the Southern Hemisphere curve to the left.

5 True/False questions

  1. Highan area in which the barometric pressure is lower than that of the surrounding air


  2. pressure gradient forceAn instrument that measures changes in air pressure, consisting of a glass tube partially filled with mercury, with its open end resting in a dish of mercury. Air pressure pushing on the mercury in the dish forces the mercury in the tube to be higher.


  3. Mercury Barometeran instrument that measure air pressure, An instrument that measures changes in air pressure without using a liquid. Changes in the shape of an airtight metal box cause a needle on the barometer dial to move.


  4. Fronta boundary between two air masses of different density, moisture, or temperature


  5. Wind Vainan instrument used to determine the direction that the wind is blowing
